Work

Selected full-stack workstreams.

These case studies come from related production workstreams inside a broader internal operations platform. I keep that shared platform visible instead of pretending they are unrelated projects, then separate each one by the engineering problem it solved.

Shared platform, different engineering depth

Shipping

Scanner/PWA validation, duplicate and wrong-shipment handling, fast feedback for handheld users.

Quality

Role-aware state transitions, current/history records, hold/release decisions, and auditability.

Visibility

Query/filter design, status summaries, admin tables, and exception-first operational views.

Artifact note: visuals, code seams, and data examples are public-safe reconstructions of production workflows. Actual UI, identifiers, customer data, and private table names are redacted.
